“…Thus, when the score on the CHAT screen was combined with clinical judgement or concern about possible autism the positive predictive value was very high even for a one-stage (CHAT-1 only) administration (71% for all ASDs and 88% for all developmental disorders). This concurs with studies that have used the CHAT screen in referred sam- ples [37][38][39] . However, sensitivity cannot be estimated from this study as the screen was not used on a total population that was then followed-up to identify screen false negatives.…”

Over the past decade our understanding of early social communication development in young children with autism has undergone a remarkable change. We now know something about how young children with autism process the social world in a very different way from typical children. This has led to truly developmental models of autism. In turn, these have had profound impacts on research and practice. Several screening instruments to prospectively identify autism have been developed. In some cases autism can be diagnosed in children as young as 2 years of age. The study of ‘high-risk’ siblings has allowed prospective study of infants from as young as 6 months of age. There is increasing evidence that intervention approaches that focus on social and communication development can ameliorate symptoms and change the developmental course of the disorder. This article will highlight some of the key theoretical and clinical lessons learned from this decade of research.

“…the proportion of false positives was high. However, the outcome for the CHAT-key-items was reversed; consistent with findings by Scambler, Rogers, and Wehner (2001), these items showed excellent specificity, especially in the oldest age group and using the highrisk criteria. As it combines a high specificity with a high PPV, the CHAT-key-items could be of use for clinicians and researchers wishing to exclude non-ASD subjects.…”

Several instruments have been developed to screen for autism spectrum disorders (ASD) in high-risk populations. However, few studies compare different instruments in one sample. Data were gathered from the Early Screening of Autistic Traits Questionnaire, Social Communication Questionnaire, Communication and Symbolic Behavior Scales-Developmental Profile, InfantToddler Checklist and key items of the Checklist for Autism in Toddlers in 238 children (mean age = 29.6 months, SD = 6.4) at risk for ASD. Discriminative properties are compared in the whole sample and in two age groups separately (8-24 months and 25-44 months). No instrument or individual item shows satisfying power in discriminating ASD from non-ASD, but pros and cons of instruments and items are discussed and directions for future research are proposed.

“…However, a 6-year follow-up study revealed that many children diagnosed with autism at age 7 had not been identified as at-risk at the 18 months screening, resulting in a sensitivity of .38 (Baird et al, 2000). Initial efforts to examine the utility of the CHAT as a Level 2 screener have also been described (Scambler, Rogers, & Wehner, 2001). The Modified Checklist for Autism in Toddlers (M-CHAT) (Robins, Fein, Barton, & Green, 2001) was originally developed as an adaptation of the CHAT and as a Level 1 screener.…”

The STAT is an interactive screening measure for autism that assesses behaviors in the areas of play, communication, and imitation skills. In Study 1, signal detection procedures were employed to identify a cutoff score for the STAT using developmentally matched groups of 2-year-old children with autism and with nonspectrum disorders. The resulting cutoff yielded high sensitivity, specificity, and predictive values for the development sample as well as for an independent validation sample. Study 2 examined psychometric properties of the STAT and revealed acceptable levels of interrater agreement, test-retest reliability, and agreement between STAT risk category and ADOS-G classification. The STAT demonstrates strong psychometric properties and shows promising utility as a Level 2 screening measure for autism.
